Rails                   
                                          
                                          
  
                                          
  
                                          
                                          
 Trains  Are  So  Constructed  That  They 
 Have To  Follow A Set Path. This Path Is 
 Called A  "Railway", Which  Is Comprised 
 Of Two Metal Rails, Hence Its  Nickname. 
                                          
 Because  The  Low  Friction  Between The 
 Wheels Of The Train And The  Rail Metal, 
 There Are  Limits For How Acute  A Curve 
 Can Be,  And Even  More  So For How Much 
 The   Ground  Under  The  Rails  Can  Be 
 Sloped. Thus A Railway  Is Often Not Led 
 On Top Of Hills,  Rather Through Them In 
 TunnelS   (If   They   Are   Large),  Or 
            Artificial ChasmS.            
                                          
 There Will Be Trees  On The  Side Of The 
 Rails, But Not Too  Close, Or They  Will 
 Be Cut  Down  By  The  Railway Janitors. 
 There  Will  Be  Plains,  And  Bodies Of 
                  Water.                  
                                          
 Trains  Go By  Day And  By Night.  Along 
      The Way, There Is Information       
 Scattered, Often  Put  On  Top Of Poles, 
 To Be Interpreted  By The Train Drivers. 
 Different  Parts  Of  The  Railway  Have 
          Different Speed Limits.         
                                          
 Sometimes, Trains Have To  Stop And Wait 
 For Something To Happen, Far  Away. This 
 Is  Signaled  By  Red Or  Green  Lights. 
                                          
                                  
                                          
 Many People  Follow The  Rails By  Foot. 
 Often  This  Proves  To Be  The  Shorter 
 Path  Between Two  Points. However  This 
 Is  Frowned  Upon,  And   Very  Impolite 
        Toward The Train Drivers!
